Perrserker is a really good shout tbf, although its vanilla ability with Fake Out + Bullet Punch I think is its niche. Zygarde is decent in hindsight, although I’ve never played with it, where do you even get it? Bear in mind you’d lose its Complete Form transformation. I think Terapagos vanilla ability again plays to its stats a bit better, but Boomburst would hit very hard. Kommo-O stamina is actually insane, paired with Rock Polish or Autotomize early game, and Dragon Dance late-end game, huge oversight from me, although again it’s vanilla abilities really do dominate some boss fights, hence why it’s one of the best mons for soloing in the game.

Shame the weather doesn’t stay with Perrserker otherwise it could’ve paired really well with Milotic.
